I hate when ppl say SAO is overrated... I felt as though it was pretty good, the first half at least.... I'd have to say Fate/Zero ... Some parts were awesome but as a whole i just found myself trying to get it over with

You just lost any credibility....Your'e trying to tell me you had to force yourself through Fate/Zero but SAO was apparently quality entertainment? You may hate it but it's the truth, SAO overall isn't good. I'm not going to hate on it because that ends with the rallying of the SAO die hard fan community. I would like to point out though it doesn't have much going for it, it's lacking any significant substance which is the reason people say it's overrated. People flock to it blindly, praising it for aspects it doesn't actually have. On the topic of Fate/Zero I'd like to say I have no idea what drug induced stupor you were in when watching it because that's a load of bullsh*t.

The second half of SAO was garbo but i liked the first half... Nah i wasn't high watching Fate/Zero but i honestly just didn't enjoy the majority of it that i watched... Maybe i'll go back and watch it again but i just could not get into it for the most part ... dunno y

Maybe it was because of the first 40-minute long episode? I was like that until I finally sat on my chair and just watched the entire episode without getting distracted. Or it's usually because SAO's a shounen anime so it's much easier to get into and marathon.

fate zero is very text head when it has no action, keep in mind that i love fate zero, but that was the biggest problem of the show, but since the show is getting dubbed we wont have that problem

No offense but there are way way too many hipsters in this thread. Sure hype and word of mouth has definitely helped out big anime titles such as bleach and naruto, but that is not the only reason for their popularity. Any long-running anime gets boring throughout the years but then they get good again, this is normal. When Bleach starts up again, whether amazing or overall boring, there will still be moments of greatness. One great episode makes up for 10 boring ones in my books. Even the more boring episodes are enjoyable for me since I just love seeing characters who have grown on me interact with each other and go about their business.

Dragon Ball series
One Piece
Bleach
Naruto
Anything with 100+ episodes really. (except for Pokemon, Inuyasha, and Ranma 1/2)
High School of the Dead
Sword Art Online (this isn't bad, but it was over-hyped)
If an anime gets a lot of hype, it most likely will NOT live up to it.

I have been watching anime in some form or another going back to Battle of the Planets in the 70's. People bash Neon Genesis Evangelion, let me tell you, when it came out it was AMAZING! The concepts were fresh and intriguing. Yes it had times when it dragged but it is still one of my favorites.
Now for overrated.... hands down the top two are any Dragonball Series and Naruto the story lines are weak excuses for the fighting, the art is lacking and well, they are just boring.
I don't understand Bleach bashing, the filler arcs are lacking compared to the main arc but they still are good (not great). There is so much more to this than the fighting, The main arc is extremely well written. As the series moves on the artwork improves dramatically. It truly evolved as it moved along. I believe it deserves the acclaim that it gets (the main arc anyhow).
One Piece...... I understand why it is liked by watching a few episodes but I don't like it.... not my style.
I have watched hundreds of series to completion..... most of them were unlicensed stuff that I had to wait for subbers for.... I can give you some truly amazing anime that will never be seen in the US. Although I must say War on Geminar is finally coming out.
